DS50PCI402: VOD settings

Zeming Kong

Part Number: DS50PCI402

Hi team,

Could you please let me know how to modify the VOD settings?

Registers only provide 4 fixed values, what should I do if I need other values?

--------------------------
03'h = 600 mV (Default)
07'h = 800 mV
0F'h = 1000 mV
1F'h = 1200 mV
--------------------------

Best,
Zeming

Hi Zeming,

You can use other values. For example for 700mV you can try 05'h. Please note in manufacturing top four typical values are checked.

Hi Zeming,

Your table is reasonable since register value versus VOD is linear. VOD settings you have noted is reasonable but may not be exact or can change from part to part since these are typical values.
